Galder Game Jam 2023

A game jam with André Søberg and Robin Berg Pettersen that found place on 3.-5.november 2023.

The Game

• galder-game-jam-2023 contains simple code to showcase a very minimal and simple game concept.
• When compiled as Debug you also get:
  • The option to go to switch maps using the F1/F2 keys.
  • Toggle infinite jump by pressing F9
  • Debug text via the debug manager.
• Player1 controls: - A/D: Move left/right. W: Jump. C: Hit. Space: Toggle sprite rotating with physics engine. Enter: Toggle camera following player. (Debug mode only)
• Player1 controls: - Left/Right: Move left/right. Up: Jump. K: Hit. L: Toggle sprite rotating with physics engine.

• The objective of the game is simple: Grab as many coins as you can before the portal opens! Fight the other player to kill him/her. Every death costs one coin. Only the player with the most coins can enter the portal and win! 🧐

• All the content for the game is located inside the content/game/content folder. All the content inside the last content folder there is copied automatically to the output bin path via CMake when the CMakeLists.txt project is loaded. If any changes are done to these files, you can make sure the last files are updated by simply reloading the CMakeLists.txt file related to raylib_template. In CLion this is as easy as right-clicking the CMakeLists.txt file and choosing Reload CMake Project.

• Maps: The maps are created using Tiled, and uses a tiled-project on the top level. If you want to modify the map files, make sure things are loaded through opening the gamedev.tiled-project in Tiled. The reason why this is important is that some types can only be resolved through the common tiled-project.

Game design document

Since the whole design process was a part of the game jam, the game design document is very limited, but we have written down the brainstorming ideas. As expected: Only a few of the ideas were small enough to fit the scope of creating a working game engine with a playable game on a weekend.

Development

• CMake is used as the build system, and CLion was used as IDE.
• Development has been done using GCC 12.1, so it's recommended to use an up-to-date version of GCC.
• The MSVC version bundled with Visual Studio 2022 v17.4.0 was used for the Windows build.
